For the clothes, not always, you can promt for what you want and / or modify it afterwards. In fact, if you want to try it, it's pretty easy to get into with automatic1111.
I'm still learning, but to get a good result, you ofter have to play around with the prompt and then run a lot of generations (about a 100 for the ones in the post).
Thanks for the ideas! I'll keep them in mind for my next post
